Abstract
Abstract A sheet front loading printer comprising a printer body with a chute beneath the body and having the inner portion bent upwards in order to guide a sheet inserted therein up to the platen. The platen also doubles as a sheet feeding device. To allow the use of sheets having a dimension less than the one defined by the path of the bottom of the chute, the chute is provided with at least one elongated opening or indentation and an arrangement of the printer supports which allows the printer to rest on a working plane. This permits further advancement of the sheet by manual action performed by the operator through the opening in the bottom of the chute.
